Abstract

A sensor-embedded display panel includes a substrate, first, second, and third light emitting elements on the substrate, the first, second, and third light emitting elements including separate, respective light emitting layers, and a light absorbing layer on the substrate, the light absorbing layer being in parallel with the light emitting layer along the surface direction of the substrate, wherein the first, second, and third light emitting elements and the light absorption sensor include a first common auxiliary layer that is continuously disposed on the light emitting layers and the light absorbing layer, and a common electrode on the first common auxiliary layer and configured to apply a common voltage to the first, second, and third light emitting elements and the light absorption sensor, and the light absorption sensor includes an n-type semiconductor layer between the light absorbing layer and the first common auxiliary layer and including an n-type semiconductor.
